Notes. Lbol LDB and Teff LDB are the locations of the LDB in terms of bolometric luminosity and effective temperature. The rest of the columns are the ages estimated using Lbol LDB and the next evolutionary models: D’Antona & Mazzitelli (1997; ‘D&M’), Burrows et al. (1993, 1997; ‘Burrows’), Siess et al. (2000; ‘Siess’), Burke et al. (2004; ‘Burke’), Allard et al. (2012; ‘BT-Settl’), and Tognelli et al. (2015; ‘Pisa’). We add in parenthesis, below each estimated age, the Teff LDB at which the LDB would be expected to be found, see Sect. 6.4. We added the LDB ages of the 32 Ori MG subsamples and sub-populations for completeness (see Appendix D).
